I support you Kairos. You can't just throw away a long history and relationship easily. Only you know if there is still something there, though if she's truly saying to go find someone else I'd have to wonder. Maybe she just wants you to be happy and thinks someone else would make you happier with all the JW stuff between you two. Or maybe she wants out herself and is telling you to get lost. It's certainly worth finding out.
You said earlier that her loyalty lies with the org instead of with you. I don't think it would be fair to make it an either/or deal. It's her thing, and you have things of your own that you're interested in. The part that hurts is that her thing hurt you and I see why you would see her sticking with it as disloyal, but perhaps seeing it differently would help relieve some tension. Install some healthy boundaries.
I feel for everyone caught in the middle with a spouse still in. I really think you two need to have some serious talks about her attitude toward the relationship, maybe get a counselor to heIp. Hopefully you can salvage it. All relationships go through ups and downs. The stress of your DFing and drama surrounding it has to have taken a hugs toll on you both. Good luck with it.
